Fish is usually kept fresh in the refrigerator, but this often changes its original flavor. To solve this problem, there are five methods: 1. Perilla leaf preservation: wrap the fish in perilla leaves and place it in a cool place; this can extend the fish's freshness, but it should not exceed 24 hours. 2. Wet grass preservation: soak rice straw or other weeds thoroughly in water, place the live fish in the middle, sprinkle water once every 4 hours, and cover the fish's eyes; the fish can live for 12 hours. 3.

3. Wine drop preservation: drop a few drops of high-proof liquor into the fish's gills or on both cheeks to make the fish drunk and fall over, then place it in a ventilated wooden box in a dark, cool place with no water; it can live for 3 days.

4. Paper-on-fish-eyes preservation: stick paper over the fish's eyes; this can keep the fish alive for about 5 hours.

5. Gas-filled preservation of fish (also called carbon dioxide preservation): put the fish into a sealed plastic bag filled with 60% carbon dioxide, 21% oxygen and 19% nitrogen; under low-temperature conditions of 0-1.1, it can be kept fresh for one month.
